The series stars Kylie Bunbury and Katheryn Winnick.
Jensen Ackles, who guest starred in the season two finale, joins the cast as a series regular in season three. The Supernatural star plays Beau Arlen, a confident and charming good ol’ boy from Texas who steps in as temporary Sheriff (and Jenny Hoyt’s new boss) as a favor to his friend Sheriff Tubb. Ackles, Deadline understands, is on a one-year deal.
Jamie-Lynn Sigler has also been upped to series regular for season three. She had a recurring role on season two as Tonya, a waitress at a local diner whose boyfriend mysteriously disappears. Tonya hired the services of Dewell & Hoyt to find her boyfriend, but soon afterward found herself stepping into power as a trusted associate of the local crime family.
In season two of Big Sky, which is based on the books by C.J. Box, private detectives Cassie Dewell (Kylie Bunbury) and Jenny Hoyt (Katheryn Winnick) reunite to investigate a car wreck outside of Helena, Montana, and they soon discover that the case might not be as straightforward as it seems. As they unravel the mystery of the accident, their worlds will collide with a band of unsuspecting teens, a flirtatious face from Jenny’s past and a vicious outsider hellbent on finding answers.
The series cast also includes Brian Geraghty, Dedee Pfeiffer, Omar Metwally and Anja Savcic.
